Hi everyone,

I'm currently simulating a transient thermal system composed of a thermistor (platinum) and a plinth (SiO2).

Internal heat is applicated to the thermistor. It sends thermal signal every 25 ms, as a square signal for electronic device.

Now i'm trying to put this system in a fluid (water) with a velocity value, to simulated the derivation of the thermal signal. I want to see until where the signal is still perceived for a temperature variation given.

When i try to put directly the transient thermal system in the fluent system, there are a lot of errors occuring..

I didn't find any tutorial for my problem, so if someone got an idea to how to do it I'm very interested !!

If my explications are not clear I can detailed them.
